This example show you how to create a LIFO (Last In First Out) Deque. We call the Deque.peekLast() method to get the last element from the Deque, poll the last element and repeat until all the elements read. package org.kodejava.util; import java.util.Deque; import java.util.LinkedList; public class DequeLifoDemo { public static void main(String[] args) { // […]

The examples below show you how to get the available catalog names in MySQL database. The available catalog names can be obtained from the DatabaseMetaData object by calling the getCatalogs() method. This method returns a ResultSet object. We iterate it and get the schema name by calling the getString() method and pass TABLE_CAT as the […]
